Temporary Strainer Pressure Drop Charts

 

Use the differential pressure charts below to estimate the approximate clean pressure drop across a temporary cone strainer or temporary basket strainer. The chart data is based on water and perforations ranging from 1/8" to 1/16".

 

To approximate the pressure drop for mesh-lined temporary cone and basket strainers, apply the following multipliers to the chart values:

 

• 40 mesh → 1.2 multiplier
• 60 mesh → 1.4 multiplier
• 80 mesh → 1.6 multiplier
• 100 mesh → 1.7 multiplier

 

Example: At 60 GPM through a 2" temporary cone or basket strainer the chart shows approximately 2 PSI clean differential. For a 60-mesh lined version the estimate becomes 2 PSI × 1.4 = 2.8 PSI.
